ASSBLY MACHINE.

Application filed June 14, 1922. Serial No. 568,332.

To all whom t may concern:

Be it known that I, DAVID S. SWARTHOUT, a citizen of the4 United States, residing at Evanston, in the county of Cook and State of illinois, have invented a new and useful Assembly Machine, of which the following is a specification.

lhis invention relates to work handling and supporting machines, the primary object of the invention being to provide means especially designed for supporting the rear ends of motor vehicles to permit the same to be repaired with facility.

Another object of the invention is to provide a device of this character having means for accomplishing the disassembling of a rear f end structure, eliminating any possibility of cracking or breaking the elements thereof.

A still further objectv of the invention is the provision of means for guarding against the loss of bolts, nuts or the like by providing screening members disposed directly under the table of the machine.

With the foregoing and other objects in view which will appear as the description proceeds, the invention residesin the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.y `l

Referring to the drawings:

Figure 1 is a plan view of a work supporting device constructed in accordance with the present-invention.

Figure 2 is a sectional view taken on line 24-2 of Figure 1;

Figure 3 is a sectional view taken on line .33V of Figure 1.

Figure 4 is a perspective View of one of the adjustable arms.

Figure 5 is a pivoted supporting arm in perspective.

Referring to the drawings in detail, the reference character 5 designates generally a work bench or supporting table which is formed with end sections 6, that are connected to central sections 7 as vby means of the langularly disposed brace bars 8.

A shelf v9 i's supported between the central sections 7 as clearly shown by Figure 2 of the drawings, which Shelf accommodates the motor 10 employed for transmitting power -to the shafts that support and move the rear end structure under operation.

Disposed under the upper portion or table of the machine, isa trough indicated at 11, which trough delivers material to the discharge spout 12, which has its lower end extending through an opening in the shelf 9 to deliver oil or foreign matter removed from the rear end structure under operation, into a receptacle or the like, positioned under the shelf rThe upper portionv of the machine includes side bars 13 and end bars 14, the side and end bars being formed with inwardly extended flanges 15 providing supports for the wire mesh material indicated Vat 16, and which covers the upper portion of the machine, providing a guard to prevent bolts, nuts or the like from falling from the rear end under operation, and becoming lost.

Disposed substantially intermediate the ends of the machine, are the transversely extended bars 17 that have their ends connected to the side bars 13, there being provided openings substantially intermediate the ends` of the bars 17, providing bearings for the threaded shafts 18.

The opposite ends of the shaft 18 are supported in the bearing members 19 which have connection with the flanges 15 of the end bars. 14. The carriages which form important features of the invention are indicated at 20 and include downwardly extended members 21 which rest on the flanges of the side bars 13. Plates 22 connect the side members 21 of each carriage, which` plates support the blocks 23 that have threaded openings to accommodate the threaded shafts 18, so that movement of the threaded shafts will result in a relative movement of the carriages longitudinally of the support.

Each support includes spaced bearingV porting surfaces 28 to accommodate thek radius rods of a motor vehicle running gear, and support the same in horizontal positions. Each of these arms is formed with elongated openings 29 that accommodate the adjusting bolts 30, whereby the arms may be held in their positions of adjustment.

The adjacent ends of the threaded shafts 18 are supplied with beveled gears 31 that mesh with the pinions 32, carried` by the stub shafts 33, which st ub shafts carry gears 34 designed to mesh with the pinion 35 carried on the movable shaft 40. The stub shafts 41 that support beveled pinions meshing with the beveled gears 31, carry gears 42 onthe outer ends thereof, whichl gears 42 may mesh with the. pinion 43 also carried on theV movable shaft 49. This movable shaft 40 extends through the side bars of the auxiliary frame 44 and carries a sprocket wheel 45, which sprocket wheel accommodates the chain 46 that moves over they sprocket wheel 47, mounted on the guide shaft of the motor 48, it being understood that the motor 48 is in circuit with a suitable source of electric supply, so that the shaft 40 may be rapidly rotated to accomplish the operation of the threaded shafts 18, for moving the carriages.

A clutch member 49 is formed on one end of the shaft 40 and cooperates with the clutch member 50 of the controlling handle 51, whereby the threaded shafts may be manually operated.

Spaced arms 52 are arranged in pairs and disposed at opposite ends of the auxiliary frame to support the horizontal rods 53 forming parts of the supports 54, the supports including curved rests 55 curved to conform to the curvature of an axle to receive they axle and support the same in a horizontal position, after the housing sections have been removed.

A curved arm indicated at 56 is formed integral with each of the rods- 53, the curved arms having pivotal connection with the controlling` rods 57 that extend in parallel relation with the upper surface of the bench or support, so that by movement of the rods 57, the supports 54 maybe moved to their active or inactive positions.

Supported at points substantially intermediate the ends of the machine are the spaced arms 58 which are pivotally mounted on the frames and adapted to be moved downwardly into parallel relation with the sides of the machine. These arms, when in their active or supporting positions extend outwardly and provide supports for the spaced bars 59 that have their outer extremities connected by means of the shaft 60, which shaft embodies drums 61 on which is wound the flexible cable 62.

that meshes with the pinion 65 carried on the shaft 60 so that upon rotary movement of the handle 66, the iexible cable 62 may be wound upon the drums 61 for purposes to be hereinafter more fully described.

The cable is designed to be positioned around the propeller shaft housing at a point Where the same connect-s with the rear axle housing of a motor vehicle so that when the cable is wound on the drums 61, the propeller shaft housing may be disconnected from the rear axle housing..

Fromthe foregoingl it will be seen that due to the construction of the shaft 40 and pinions mounted thereon, the shaft may be moved with respect to the upper portion ofv the machine to bring either of the pinions 35 or 43 into operation for rotating the threaded shafts 18 in predetermined directions.

When a rear end construction is sup'- ported on the carriages, and the bolts which connect the differential housing sections have been removed, power may be applied to theV shaft 40 to cause the threaded shafts 18 to move the carriages away from each other, with the result that the rear axle is exposed and may be easily repaired.

When the axle has been repaired; it isv obvious that by rotating the threaded shaft 18 in the opposite directions, the carriages together with the rear axle housing sections may be moved towards each other where they may be bolted together.

It might be further stated that trays such as indicated at 67 may be secured: to the upper portion of the machine for the convenience of the operator, providing a place to lay tools, bolts or the like.

Having thus described the invention, what is'claim'ed as new is 1. In a machine of the class described, opposed threaded shafts, carriages movable along the upper surface of the machine, blocks having threaded openings to accommodate the shafts, mounted on the carriages, whereby movement of the shafts will cause the carriages to move towards and away from each other, pivoted supporting arms mounted adjacent to the inner ends of the shafts, and means for rotating the threaded shafts. l

2. In a machine of the class described, threaded shafts, carriages having threaded openings to receive the shafts, saidv carriages adapted to support an axle housing, means for rotating the shafts to move the Acarriages longitudinally of the machine, means for clamping an axle housing to the carriages, and pi'voted supporting members associated with the carriages and adapted to be moved' to support an axle.

3. In a machine of the class described, carriages supported by the machine, means for securing an axle housing to the carriages, means for moving .the carriages longitudinally of the machine, to separate the axle housing, and pivoted supporting arms adapted to support an axle exposed by the moving of the axle and said pivoted supporting arms adapted to operate independently of the carriages.

4. 1n a machine of the class described, movable carriages mounted on the upper surace of the machine, threaded shafts hav- 10 ing connection with the carriages for moving the carriages towards and away from each other, and means for moving an yarticle laterally of the machine.

In testimony that I claim the foregoing as my own, I have hereto axed my signa- 15 ture in the presence of two witnesses.
